DISPENSING RECEPTACLE FOR ADHESIVES Filed Sept. 23, 1927 Patented Oct.8, 1929 rar 'rY oFIcE JOHN E. R. HAYES, OF MELROSE, MASSACHUSETTS,ASSIGNOR TO TI-IE CARTERS INK COMPANY, OF CAMBRIDGE, MASSACHUSETTS, ACORPORATION OF MASSACHUSETTS DISPENSING RECEPTACIE FOR ADI'IIESIV'IESyAppncanon fusa september 23, 1927. sei-iai No. 221,585.

The invention relates to an improvement in dispensing receptacles foradhesives especially mucilage. The present receptacle is one of thattype which is substantially airtight and is provided with avalve-controlled port or opening through which the mucilage may bedispensed on opening the valve by pressure applied to it Jfrom outsidethe receptacle, and one obj ect of the invention is to provide avery.simple means for retaining this valve. A further object of theinvention is to provide means whereby air may be admitted to theinterior of the receptacle at the same time that the mucilage is beingdispensed therefrom on opening the valve.

The invention can bestl be seen and understood by reference to thedrawings in which- Figure l is a side elevation of the dispensingreceptacle.

Fig. 2 is a cross vertical section of the head of the receptacle withattachedcap, the conv tained spring` being shown in front elevation.

Fig. Sis a vertical cross section like that of Fig. 2, but taken on aline substantially at right angles to the line ot the cross section otFig. 2.

Fig. 4 is a plan of the receptacle, and

Fig. 5 is a view mainly in side elevation and partly in section showingone method of using the recept-acle.

l represents the body of the receptacle consisting preferably of abottle of any common type. Attached to the top open end oi this bottleclosing it is a cap 2. This cap comprises a crown or dome 3, a rim 4land a downturned lange 5. The rim l lits against the top end of thebottle. The flange 5 is the means by which the cap is secured to the topend of the bottle, the flange being attached thereto in anysuitablefmanner and preferably by providing the flange with indentations6 which :fit within sockets 7 formed in the wall of the bottle.

The crown 3 of the cap is provided in its sides with port openings 8oppositely arranged. These openings are each preferably formed i nflattened portions 9 on opposite sides of the crown and lie below thetop thereof. Each of these openings is controlled by a valve 10 whichprojects through the opening to protrude beyond the outer 'ace of the.dome when the valve is closed, the valve being provided on its inner endwith a skirt ll which seats against the inner edge of the dome aroundthe opening in it or closing the opening.

As just explained, there are two openings and two valves each valvecontrolling an opening. The valves are both held normally closed and atthe same time yieldingly held so that either valve may be opened bycompressing the protruding end thereof against an eX- terior objectthereby unseating and opening the valve by means of a bent spring l2common to both. The ends of the spring areseated in the respectivevalves, the body of the spring lying` interposed and tensioned betweenthem, the spring holding in place by its own tension. curved springsubstantially as shown with body lying pendent within the cavity of thedome.

In operation either valve may be opened by-pressing it against an objectto which the mucilage is to be applied, the eect of such pressure beingto open the valve and allow the'mucilage to escape. The elasticity ofthe spring permits such opening and when the pressure. is relieved thevalve will immediately be returned to a closed position by the'spring.y

The advantage of using two valves resides not only in that one valveprovides a seating or mounting for the end of the spring which retainsthe other valve, but also in the fact that when onefvalve is beingopened for dispensing mucilage through the opening controlled by it, theother valve may also be opened by pressure applied to it by the lingerof the operator, thereby allowing air to enter the chamber-ot the bottleand resulting in a freer flow of mucilage as may be desired. In ordinaryuse itwill be unnecessary to open the second valve for admitting air,but in cases where a considerable amount of muoilage is desired then airmay be admitted fo obtaining an increased flow.

The arrangement of the valves permits of the cap being provided with aspreading surface lying between and above the valves and The spring ispreferably a a dome provided with separate port openingsV therein,outwardly closing valves controlling said openings, and a bent springmounted upon and tensioned between said valves` whereby the spring willbe held in place by its own tension and the valves in a normally closedposition with permitted opening of either, or both simultaneously.

2. In a dispensing receptacle of the 'type specified, the combinationcomprising the body of the receptacle, a cap closing it having a domeprovided with separate port'openings therein oppositely arranged,outwardly closing valves controlling said openings and with extensiontherethrough when closed, a bent spring tensioned between said valveswith ends seated within said valves respectively whereby the spring willbe retained by its own tension and the valves in a normally closedposition with permitted opening.

3. In a dispensing receptacle or` the type speoied, the combinationcomprising the body of the receptacle, a cap closing it having a domeprovided with port openings in the opposite side thereof, and a topspreading surface lying between said openings, outwardly Closing valvescontrolling said openlngs, and a bent Vspring mounted upon and tensionedbetween said valves whereby the springlwill be held in place by its ownten-V sion and the valves normally closed with permitted opening.
